APPARATUS FOR DRESSING FABRICS.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed Cctober 11, 1910. Serial No. 586,540.

Q'b all whom it may concern:

Be it known that we, Memos RA'rIGNInR and Hexer Pnnvinnao, citizens of the French Republic, residing, respectively, at Lyon and Villeurbanne, Rhone, both in France, have invented certain new and useful Improvements in Apparatus for Dress ing Fabrics, of which the following is a specification.

rlhe present invention relates to apparatus for spreading dressing on the surface of tulle and like fabric by means of brushes having a transverse movement, and arranged symmetrically one above the other on each surface of the fabric, said brushes being adapted to spread the dressing in a continuous manner and in quantities which may be varied according to requirements.

An embodiment of the invention is illustrat'cd in the accompanying drawings, in which Figure l is a transverse section of part4 of the machine showing the brushes. Fig. 2 is a plan view of said part of the machine. Fig. 3 is an elevation on a slightly smaller scale, showing an example 0f mechanism for operating the brushes. Fig. 4l is a plan view of Fig. 3.

The fabric t is drawn through the machine in the usual manner by means of chains a a carrying pins al which travel at distances apart according to the width of the fabric. The movement of the fabric and the guiding thereof is eiiected in the known manner.

The upper brushes b b are mounted to the number of two or more on a slide or carriage c adapted for movement on two metal wires f f stretched transversely across the machine above the fabric. The lower brushes 1 which equal in number the upper brushes are similarly arranged below the fabric on a carriage or slide c1 adapted forl movement on the stretched wires f1 similar to the wires f. The two carriages between which passes the fabric to be dressed are each given a reciprocating movement from one side of the machine to the other during which time each pair b and b1 are continu ously superposed, the fabric being held and acted on by the brushes on both surfaces. The brushes are supplied with the dressing material during their movement by means of two endless transverse cords g g1, which pass one above and the other below the fabric in guides a2 carried by the beams Z disposed and traverse the brushes near their free ends. The said cords g g1 are guided by suitable rollers conveniently mounted and are operated at a variable speed by means of a longitudinal shaft 7L, their upper stretches moving in opposite directions and in such a manner that they cross at the center of the fabric as shown in Fig. Q. Both cords become coated with the dressing material by passing over grooved pulleys i z'l rotatable in receptacles j jl containing said material. lt will be obvious that each cord as it travels in a path which is inclined with regard to that traversed by the brushes, will transmit the dressing material to said brushes along the whole or substantially the whole length thereof, and that the supply of the dressing material will be increased the greater the speed of the cords g g1. The distribution of the dressing material can thus be regulated by controlling the speed of the shaft 7L which may be driven by an independent motor or by a variable speed transmission gear.

The apparatus above described may be repeated or duplicated as often as necessary along the length of the machine to supply the necessary quantity of dressing and to convenient-ly regulate the supply.

The reciprocatory movementof the brushes may be produced by any known mechanism capable of acting on all the brushes at once by means of suitable transmission gearing or can be repeated for each brush or series of brushes as may be desired.

For the most effective spreading of the dressing material it is preferable that the brushes are given uniform movement which may be effected by means of the mechanism shown in Figs. 8 and 4. This mechanism is shown as applied to the carriage 01 carrying the brushes o1 acting on the lower surface of the fabric t. Located below said carriage is an endless belt Z passing over two horizontal pulleys m m and traversing` the machine from one side to the other. At a suitable position on this belt a vertical finger e is fixed traversing a slot or guide el in the carriage c1. rlhe belt Z being put in movement in one direction or the other the carriage c1 will be given a reciprocating` movement the speed of which will be uniform during its strokes in both directions. The upper brushes b which remain exactly superposed relatively to the brushes b1 may be actuated by similar mechanism by replacing the belts by endless chains but is more simple to transmit the movements of the lower carriage c, vto the upper carriage 0 by means of cords n n disposed as shown in Fig. 4. The said 'cords pass over pulleys p 29 rendering the movements of the two carriages absolutely "simultaneous.

That we claim as our invention and desire to secure by Letters Patent of the United States isl. In a machine for dressing fabrics the combination of a pair of superposed brushes adapted to he g'iven reciprocatory movement and between which the fabric is fed, means for supplying dressing material to said brushes comprising iexible members traversing same and means for imparting variable movements to said flexible members.

2. In a machine for dressing `fabrics the combination of a pair of superposed brushes adapted to be given -reciprocatory movement in unison, and between which the material y is fed in one direction, means for supplying dressing material to said brushes comprising cords tiaversing said brushes, and means for imparting movements in opposite direct-ions and at- -variable speeds to said cords.

3. In a machine for dressing fabrics the vcombination of a pair of superposed brushes adapted to be given reciprocatory movement and between which the fabric is fed, means for supplying' dressing material to said b'rusl'i'es 'comprising fiexible members traversing same said flexible members moving in paths inclined to that of the brushes, and means for imparting variable movements to said flexible members.

4. In a machine for dressing fabrics the combination of a pair of super-posed brushes between which the fabric is fed, means for supplying dressing material to said brushes comprising flexible members ltraversing same, m'eans yfor imparting uniform reciprocatory movement to the lower brush of the pair, and meansfor imparting said uniform ymovement from the lower brush to the upper brush.
